100 POINTS Use the function f(x) = 5x2 + 2x − 3 to answer the questions. Part A: Completely factor f(x). (2 points) Part B: What are the x-intercepts of the graph of f(x)? Show your work. (2 points) Part C: Describe the end behavior of the graph of f(x). Explain. (2 points) Part D: What are the steps you would use to graph f(x)? Justify that you can use the answers obtained in Part B and Part C to draw the graph. (4 points)

see below

Step-by-step explanation:

f(x) = 5x^2 + 2x − 3

        (5x-3) ( x+1)

To find the x intercepts, set this equal to zero

0=  (5x-3) ( x+1)

Using the zero product property

5x-3 =0     x+1 =0

5x=3             x =-1

x = 3/5             x = -1     are the zeros

End behavior

x = -infinity

5 ( -infinity )^2

5 (infinity) = infinity

as x goes to negative infinity, f(x) goes to infinity

x = infinity

5 ( infinity )^2

5 (infinity) = infinity

as x goes to  infinity, f(x) goes to infinity

To plot the function, we need to plot the zeros ( or x intercepts) and the end behavior as well as the vertex to plot the graph

it can be to see completed examples before writing, in order to examine what makes for an effective piece. see how these intros give some context before posing the topic and lead naturally into the body paragraphs, where the evidence will be listed. you can imagine how the author has organized the rest of the piece.

"we buried my cousin last summer. he was 32 when he hanged himself from a closet coat rack in the throes of alcoholism, the fourth of my blood relatives to die prematurely from this deadly disease. if america issued drinking licenses, those four men—including my father, who died at 54 of liver failure—might be alive today. that is a good example piece   some steps that are .

. writing something that happened to you

.read a book you like to get ideas from there

. lastly you can make a venn diagram

hope this plz make brainliest
